The ISS-105 IS Super Cell
is a “smart” five-channel intrinsically safe relay
and pump controller. The IS Super Cell can be
configured for a wide variety of applications
including alternating or non-alternating duplex,
duplex separate pump stop (SPS), triplex and
quadplex applications. It can be set up for pump-
up or pump-down applications or can be used as a
five-channel relay.
The IS Super Cell has a long list of features that
are needed for multiple pump applications. The
IS Super Cell can indicate low, high and out-
of-sequence alarms. If an out-of-sequence alarm
occurs, the skipped pump(s) will be started as
intended. The Model ISS-105 can be set up to
do non-alternating control, alternating control
and alternating control with one non-alternating
pump. The non-alternating pump is intended for
use with an emergency or jockey pump. The
IS Super Cell can start an emergency pump
once every 50 cycles to keep it working freely
Using the built-in DIP switches, individual
pumps can be disabled when taken out of
service for repair or maintenance.

See Appendix A, page 70, Figure 13 for dimensional
drawing.
